Answer:
Explanation:
3 + 2x - y = 0
Or 2x - y = -3 (1)
-3-7y = 10x
Or -10x - 7y = 3 (2)
2x - y = -3 (1)
-10x - 7y = 3 (2)
———————
Multiply 5 to (1)
5(2x - y = -3)
-10x - 7y = 3
———————
10x - 5y = -15
-10x - 7y = 3
———————
-12y = -12
y = -12/-12
y = 1
Plug y value in (1)
2x - 1 = -3
2x = -3 + 1
2x = -2
x = -2/2 = -1
Therefore, x = -1 and y = 1
Answer:
By angle sum property,
56 + 92 = 148
180 - 148 = 32
linear pair
so , 180 - 32
= 148

Answer:
<u><em>0.006 cents</em></u>
Step-by-step explanation:
divide 1.20 with 200
since a unit price is 1 of something
so 1.20 divided by 200 = 0.006 cents.
0.006 is your answer.
You can multiply everything by 7 to make things simpler.
3x + 5 = 4
3x = -1
x = -1/3
'what number' indicates an unknown value we can represent with 'x'
'is' indicates an equal sign.
25% = 0.25
'of' indicates multiplication.
x = 0.25 * 180
x = 45
